In France April 13, 1933 i 6 Claims (01. 4- 47) The invention relates to lavatories with seats and has for its aim to provide all desirable comfort to persons using the same, from thepoint .of view of cleanliness and hygiene, protecting 5 them entirely from the risks incurred in known installations of contracting very serious infectious diseases, particularly in hotels, trains, public lavatories and the like. Further, the present invention has the very' important advantage of not requiring the user to'perfor'm any complicated manipulation and particularlythe handling of objects which have previously been soiled by others. ,This constitutes an important progress in public health without causing any inconvenience to those who benefit thereby. For this purpose the invention includes means which areccmbin'ed with the seat of the water closet panand arranged and designed in such a way as'to'ensure automatically before, orafter, each use of the sanitary apparatus, the placing into position of a protective seat covering, which may for examplebe of paper, and the removal of the seat covering" which has been used.

According to one form of application of the invention the device includes, for each side of the seat, a seat covering band of paper delivered from a supply roller and which is woundup on a rewind roller after. having passed over the seat, the movement of the rewind rollers being efiected by means of a suitable mechanism.

The invention also relatesto means for the removal of the device and its easy and rapid fitting on all kinds of pans; tomean'sfor actuating the rewind rollers for. the "seat covering bands, and the arrangement of spools and spool supports'for the said'bands, as'well'as means for raising the seat automatically.

Several forms of application of the present invention are described hereinafter andare shown schematically, by way of an example, in the attached drawings, in which: a 1

In thesejfigui'es l s thepan and! is t he'iseat '5, that can be lowered, said seat being shaped aocording to an opening 3 and pivoting-by the lugs 5, about an axles mounted in fixed supports 6. j

A solid lid 3 is arranged on the ee: i sojthat it can pivot onpins I. v I v I According to the inventionythe seat andmthe lid are. providedwith means which are sol der signedand arranged that, each time that thelid 8 i r i ed. 9 thaws @QiWWLfiPWW 9 used, "this-necessary operation results in the auply roller 19 carrying a roll of paper 9 from' which the paper unrolls and passes over the corresponding side of the seat on which it forms a protective seat covering band 9a, which later on will wind itself up on the rewind rolier H provided for the paper which has been used.

The two supply rollers 10 are so xmounted that they can'be removed for replacing the rolls between the support plates l2 and 13 which are fixed on the seat 2, each of said rolls being supported-by a shaft !4 arranged between the plate I2 and another plate 33 which is also: fixed on the seat. j Thetwo rewind rollers H are also mounted between the plates l2 and I3 in such a way as to allow the ,used'paper to be removedQand each of said rollers isrotated by a shaft 15. The plates l2 and I3 form the extreme vertical sides of the roll covering case 16 having perpendicularly to the opening 3 of the seat 2, a corresponding opening closed laterally by the plates 34 with a'slot I! through which the paper 9-can pass. The shafts I5 are actuated by means of a mechanism arranged in a rear case 18, defined at the front by the foundation plate 33 and at the rear by thefoundation plate l9. This mechanism includes a ratchet wheel 29 mounted freely on a shaft'2l fonwhich is freely mounted a lever 22 carrying a pawlj23 which engages with the teeth of theratchet wheel integralwith a gear wheel 24 also mounted'loosely on the axle 2| and which is in meshwith a gear wheel 25 keyed on to the shaft 15.

By tipping the lid 8 upwards, the two ratchet wheels 23 are automatically actuated and, for this purpose, the'device includes, for. example, a .drivingplate 26 which isarranged slidably between the'vertical guides 21 and is provided with two actuating pins'I-ZB engaged between the pronged ends of the'levers 22 which carry the pawls, the said plate 26 being suspended in its .centre from a cable 29 passing over a guide pul ley 30 mounted on the upper part of the rear case 18 and then over the lower guide pulleys 3| and thesaid cable being attached by its other end to 32 on the inner face. of theglid 8. The working of. the device is therefore easily understood. V g I When the user lifts the lid 8 this causes the I plate 26 to move upwards to the position 26 and by means of the pins 28 to displace the levers 22, which carry the pawls, to the position 2 2, thus actuating the ratchet wheels 29, the movement of which is transmitted by the toothed wheels 24and 25 to the shafts l5 rotating the rollers l I. In this way thelatter cause the unwinding of acertain length of clean paper from oifthe supply rollers -.|0,fwhilst the paper which has been used moves away'fromthe sides 2a and 2b and makes room for the clean paper. 1

to the position shown in full lines in Fig. 7 and the pawls 23 pass over the teeth of the ratchet wheels 29.

With regard to the auxiliary means for mounting the protective apparatus (Figs. 11-16), they consist of a plate 36 provided with bolts 31 which can slide in grooves 38, thus making it possible to adjust the distance between the said bolts so that it will correspond to that of the pan to which the protective device is to be fitted. On the plate 36 is superposed another plate 40 which is provided with grooves 4| in which engage the bolts 42 which are screwed into the plate 36. The second plate 49 moreover is provided with gudgeons 43 which act as pivot pins and which cooperate'with the lugs 39 of the rear case I8 of the protective device. As a result, owing to the adjustment provided by means of the grooves 4 l it is possible to fix the plate 40 at the desired place on to the plate 36 thus ensuring that the protective device will, at the front, come to the edge of the pan, no matter what the length of the pan itself may be. I

With regard to the actuating mechanism for the rewind rollers H by the movement of the lid 8,

the arrangement shown in Figs. 17-19 is simpler than that described above and as shown in Fig. 7. The lid 8 is provided with a support 44 on which are pivoted two rods 45 each of which is pivoted at its other end on a sliding member 46 which is provided with a roller 41 engaged by the forked head 48 of a balanced lever 49 pivoted at 50, the other end of which is provided with a pin 51 engaging with the fork end of the lever 22, the pawl 23 of which moves the ratchet wheel 20 actuating the driving shaft l5.

With regard to the seat covering bands, these are arranged on tubes 52 (Figs.,20-23) made of cardboard or other suitable material and provided with a longitudinal slot 54 into'which the end of-the paper band which is to be rolled up is inserted. At its ends, the tube 52 is provided with notches 53 into which fit the actuating members which Will be explained hereinafter. The use of such tubes in the protective device means a considerable saving and also allows of thevery rapid replacing of'the rollers in an analogous manner to those in photographic cameras. The rewindrollers being thus formed by the said tubes 52, the supply rollers may consist either of one single piece (Fig.22), the supply of paper 9 being wound directly on to the tube 52, or of two pieces (Fig. 23) the supply of paper 9 being wound on to an ordinary tube55 which is then slid on to the tube 52. 1

With regard to the mounting of the supply and rewind roller tubes, (Fig. 24) this is carried out as follows: I The tubes are introduced between the supporting plates I2 and 13 on to the tube carriers 55.

The supply roller, which must rotate freely on the shaft 14,: is mountedon the side of the plate I3 by means of a muff 51 sliding on the shaft 14 and under the influence of a spring 61. On the ,endof this muff are arranged a fibre plate 58 and a carrier 59 on to which is fitted the tube 52 andwhichturns freely on the fixed shaft 14, the friction against the plate 58 acting as a brake. :on' the side of the-plate !2 there is the same arrangement of carrier 59 and plate 58. As a'result of this arrangement, the feed roller-is influenced by abraking action, due to, the spring 6|, between the fibre plates 58 and this will give the necessary tension to the seat covering band.

As regards the rewind roller, the carrier 59,

although arranged slidably, is integral with the driving shaft 15 with which it rotates, and there is no friction plate. On the side of the plate l2 the carrier rests preferably on a thrust ball bearing 60.

It is evident that the actuating of the protective device, instead of originating from the movement of the lid, can be derived from other members and particularly can it be carried out by the movement of the seat, if the latter is pivotally arranged.

It is possible in fact to leave the seat in a raised position normally, so that the pan is open and can be used as a urinal.

In this case several devices can be used in order to ensure the automatic raising of the seat.

In the example shown in Figs. 25 and 26 the movable seat 2 is fixed on the case 18 which is pivotally arranged at 8! and is provided with a right angle extension 82 which is under the influence of a spring 62 arranged in a telescopic tube'83 and provided with the tension adjuster 63, fixed on a lever 19. This lever 19 is pivotally mounted '13 at the end of a support 56 which is affixed by the bolts H or by some other means to the plate 36; the said lever "19 terminating at the end which is remote from the point of attachment of the spring 52 in a pivot head or foot 80 which rests all the more heavily on the ground as the load of the spring 62 increases. This arrangement ensures a greater rigidity of the support 76 and besides renders it unnecessary to make a. hole in the floor for the purpose of fixing the said support. 7

When the user lowers the seat -2, an arm 54, which is pivoted on the extension 82 of the case l8 will be supponted on the head 65 of a lever 66 pivoted at M on the support 16.

It is therefore easily to be'understood the, when the lever 66 is so displaced that it allows the end of the arm 64 to escape from the head 65, the seat 2 will rise automatically under the action of the spring 62.

This displacement of the lever 55 can be eflected in various ways. For instance, it is possible to attach to the end which is remote to the head 65, a chain 15 connected to a two armed lever 13 to which is attached the chain '52 of the water flush, so that the seat will rise automatically when the chain 12 is pulled (fig. 25).

Also it is possible to provide an actuating bar 69 which, when the seat is lowered, engages with a pin 6'! on the lever the said bar being displaced by the operation of a handle 68. By pull- 'ing on this handle 68 the disengagement of the seat 2 is effected.

, Further it is possible to: provide an arrangement which ensures this release automatically in the event of the user having neglected to carry out any operations. For this purpose a chain 19 is connected at the one end to a rearwardly extending lever attached to the handle 68 and at the other end to the door of the premises. As an accessory it is possible to fix a chain H, for example, to the pivoting point I of the lid 8 and to the lever of the water flush so as to ensure the discharge of the flush automatically when the apparatus rises again.

It is'clear that other variations and improvements of details can be conceived without going outside the limits of the invention.

' In particular the protective sheets So, instead of being unwound from off the roller l and being wound on to the rewind roller H, could be onwound from a reserve roller by a traction device consisting of a combination of rollers of ,difierent diameters, as in typewriting machines, the paper being pulled over the sides 2a and 2b of the seat, the used part being cut off automatically so that it will fall into the pan.

means, first removes the seat covering'which has beenused and allows it to fall into the pan, after which it places in position a fresh seat covering and cuts the strips which connect it with the remainder on the supply roller. f
